Products Description of Swing Check Valve

Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.

The main structure features of Swing Check Valve:

1The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2
Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based 
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3
Small opening pressure, the disc can be opened fully with a very small pressure differential.
4
Inside-set bolt-bearing structure reduces leakage and reliable use.
5
PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along 
with the pressure rise so as to ensure the sealing performance.
6
Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

Q:hello my names matt and i have a 1997 eclipse 2.0 non turbo with 94k miles and the semi circul seal on my valve cover gasket has a small leak that i see oil dripping and i dont think the pcv valve has ever bin replaced could any of those cause my exhaust to burn oil maby a bad fuel injector? theres no oil in the top of the engine on the spark plugs when i check them all, the piston rings and the headgasket r not worn or cracked so idk what it could be some one please help
a leaking valve cover could only cause oil to burn when it drip,s onto the exhaust manifold that would be mainly under your hood...a plugged or bad P.C.V valve could cause crankcase pressure to build could cause minor oil consumption....if your sure your piston ring,s are in good condition then the valve seal,s would be the next suspect...change your positive crankcase ventilation valve first.....it would help to know more detail...like...does it burn more at start up or hard acceleration...that would indicate valve seal,s or guide,s....another thing would be just how much oil does it consume per mile....more detail will insure a more accurate answer...good luck!
Q:What is the easiest and best way to fix a leaking shut-off valve on a toilet?
Take out the old one. it is easy it just slides up the over flow tube go to a hardware store and get a replacement ball valve (Ballcock) they are just a couple bucks.slide the new one on! Take the old one when you go to get the new one.
Q:What kind of valve is on this tennis ball cannon in this picture?
It's a pneumatic valve with a compressed air tank to power the cannon. Any kind of pneumatic valve should do the trick, just make sure you use the correct fittings for whatever valve you buy. The red lever piece is from a standard pressurized air system for a mechanic's shop. It is probably only necessary as a safety mechanism to discharge the air without shooting the ball.
Q:If this prolapse considered heart disease. I was diagnosed years ago with it . My doctor at the time told me this is not heart disease and now I googled it and it said this is heart disease. Another person said this is valve disease ? I never asked my current doctor if it was or not. She checks me every 3 months because I have a heart murmur that you can have with this prolapse. whenever I have filled out questionaires about health history when they ask me if I have heart disease I always check no. If this considered heart disease or valve disease. I've never been to a cardiologist for it. Should a person have at least one evaluation from a cardiologist for this ?
Its a valve disease. It is a valve between the right atria and right ventricle within the heart muscle. Mitral valve prolapse simply is the fact that the valve does not completly close once the blood is pushed down from the atria where the deoxygenated blood is where the new oxygenated blood will be after it goes through the pulminart artery to collect oxygen from the lungs, then comes back to the ventricle. What then happens because of the prolapse is it has a little regurgitation, or spitting back up some fresh oxygenated blood back to the atria, and then continues to the left atria through the corniary vein. Hope that explains why its more of a valve disease than the heart disease. Heart disease has to deal with the heart muscle. And its chambers. Then you have corniary artery disease which focuses on the arteries and veins of the heart and of course the valves which includes your aorta, bicuspid (mitral valve), and your tricuspid.
Q:Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.
Valves make a ticking noise due to: -normal wear -faulty lifter -faulty valve spring
Q:HAS ANYONE HAD VALVE REPLACEMENT (WITH PIG VALVE) OPEN HEART SURGURY. WHAT WAS THE RESULTS? HOW DO YOU FEEL NOW?
Pig valves and Cow valves are the tried and tested valve replacements used for longtime. These work well and have minimum post-surgery problems.. Go ahead.. Al the best..
Q:i got a filler neck for my dodge dakota and was wondering how to put it on. can anyone send me a link or help me. and also what does my EGR valve look like and i cant seem to find a new one not even at the dealer. i was told to clean it how do i do this. can someone send me a link or pic what it look like. thanks
The VECI decal map under your hodd will show you EXACTLY where your EGR valve is. You may need a magnifying glass. The valve can be removed and cleaned with Gum-out or foaming cleaner (amsoil). When you are done, re-install the valve. While you are getting ambitious, clean your throttle body and plate, and the IDLE AIR CONTROL VALVE. A dirty IAC is the most prominant reason for the EGR valve to clog up. Running Gum-out through your intake system will clean out your O2 sensors, as well. Good luck!!
Q:1998 Ford Crown Victoria LX 4.6L Use 89 Octane BP, Shell, Chevron gas. When the engine is under stress(acceleration or going up incline) the engine sounds like the valves are chattering. I can increase the rpm's and the chattering goes away. Had the same problem with 95 Thunderbird 4.6 and have heard other ford cars going down the road with this problem. Air leak? Don't really want to use higher octane due to gas prices and possible engine damage. Also, in the thunderbird, i used a bottle of octane boost and the next day a valve spring broke. Was the octane boost a possible cause?
it is not valve chatter, it is called Pinging, it is a fairly common problem, what it is caused by is hot spots in the engine, or by overly advanced spark timing, i would check your base timing, perhaps even back it off a degree or two, i would also run a bottle of marvel mystery oil, or gm top engine cleaner through a vacuum line to burn out the crud that has built up, the sum total of these repairs: about 15 bucks, the savings: your engine! as for your t-bird, it was the pinging that broke the valve spring, not the tank of hi octane. hope this helps
Q:My car hesitates on the highway 55 m/h and up after about 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem went away after disconnected the Egr, so is it for sure that the valve is bad? Just wanted to make sure there's no other component that could be also be bad. I have a toyota avalon 1997.
You might be able to get the valve cleaned by spraying cleaner in it or by emersing it in solvent. Check the repair manual and consult with an experienced mechanic. I don't even have a ball park figure of what a new one would cost.
Q:I bought a plastic ball valve from Lowe's just a couple days ago and it is stuck, I haven't installed it in anything but it wont budge without a pair of channel locks. I tried wd-40 but still nothing, should I return it or keep working with it? and if I keep working what should I try?
=== take it back and get another valve .... if it doesn't work freely in your hand then the valve will be a problem if you install it ---- working with pvc you should use the purple glue that is waterproof and it is a good seal and no leaks when you have
